1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

objectivesWe conducted a study comparing full sternotomy (FS) and minithoracotomy (MT) for aortic valve replacement (AVR). The primary end-point was determining all-cause mortality and other variables according to the VARC 3 Consortium.

methodsRetrospective investigation from January 2017 to December 2024 in 2 referral centres in Peru. We selected 142 patients who were submitted to isolated AVR through MT and 772 through FS. We used unmatched analysis and a propensity score matching (PSM) for matched analysis.

resultsIn the unmatched analysis, operative mortality for MT was similar (MT: 2.1% vs FS: 1.6%, P: .391), stroke rate in the MT group was 2.1% and in the FS group 1% (P: .278), pacemaker insertion was more common in the MT group (MT: 3.5% vs FS: 0.5%, P < .001) as well as post-operative atrial fibrillation (POAF) (19% vs 9.2%, P < .001). After a PMS, operative mortality was similar (MT: 1/108, 0.9% vs FS: 3/108, 2.8%, P: .314); as well as, pacemaker insertion (MT: 2.8% vs FS: 0%, P: .081), stroke (MT: 1.9% vs FS: 0%, P: .162) or POAF (MT: 15.7%, FS: 8.33%, P: .086). At follow-up, PMS analysis showed a similar 5-year survival estimates (MT: 97.6%, IC 95%: 90.7%-99.4% and for FS: 94%, IC 95%: 85.2%-97.6%, P: .103).

conclusionsIsolated AVR through MT or FS has similar operative and follow-up mortality rates. It is possible to implement a minimally invasive cardiac surgery (MICS) program with good results in middle-income countries.
